Run testcase in chain

Hello there, anyone can help me to run the testcases in chain, it quit the app with each time the test cases runs, i want to run the cases all in once with out quitting the app

that does not make any sense 99% of the time, you are unlikely to get help to do something that nobody does, because almost nobody tests that way because it means you are not testing in a “sandbox”. State from one test will overflow into the next test and you will waste loads of time.
